i typed a literal comma, and then the tab button, and it put in the baker's dozen other characters. I only did this to see if "this doesn't work in powershell" was true, turns out it is not true.
if i have ,foo.exe and ,cuda_install.exe in a directory (or on my path), it's two characters and then a tab, same as linux, to run either of them: ,c || ,f
